According to the regional (IASAUDE) and national (DGS) health authorities, although Madeira has a resident Aedes aegypti mosquito population, there have been no reports of Zika virus in Madeira, with the only cases reported being imported cases.

Jaime Nina, virologist from the national institute of higiene and tropical medicine (Instituto de Higiene e Medicina Tropical) suggests in an article in the regional news paper Diário de Noticias on 29 January 2016 that it would be a good time to try and eradicate Aedes from Madeira. The expected and normal increase in vector mosquito activity in September could be an issue.

Ana Nunes from IASAUDE confirms that:

Madeira maintains a network of 193 traps to monitor the population of Aedes mosquito

none of the Zika cases reported in Portugal were in Madeira

that the best practices as recommended both by national DGS and international CDC are in place, including educating the population and implementing preventative measures.
